Nginx is simple to use, yet a powerful web server. If you’d like to search through its official documentation for a term that you couldn’t understand or just wanted to learn the syntax of a keyword, you don’t have to search through the entire Nginx documentation site. Instead, you could use the shortcut https://nginx.org/r/keyword . You may replace the keyword with the actual keyword. For example, in order to find information about rewrite, you could type https://nginx.org/r/rewrite to get to https://nginx.org/en/docs/http/ngx_http_rewrite_module.html#rewrite .
When someone uses https://nginx.org/r/keyword, it also detects the user language, and redirects the documentation in that language (if it exists, of course). For example, if you are in Russia and if you search for the keyword rewrite, you’d get redirected to the Russian version of the same page at https://nginx.org/ru/docs/http/ngx_http_rewrite_module.html#rewrite .
A huge time-saver!
